QuickPrint offers custom, up-to-date catalogues of Sun products. Back pressure may adversely affect the operation of a standard non-vented counterbalance as it directly increases the valve setting, opposing pilot pressure. With vented valves, a lower pilot ratio may be required to achieve machine stability compared to non-vented valves. This valve has positive seals between all ports. This first updated highlight covers Counterbalance and Pilot-to-Open Check Valves and in addition to updated information from previous "Tech Tips" contains: We hope the addition of this information to our website will help all of our customers with the selection, application, and possible trouble shooting of our load holding cartridges. A counterbalance valve can easily be described as a pilot operated relief valve with a free flow check.

Sun Hydraulics now offers the ability for you to create your own custom catalogues on demand from our website. Page 1 of 16. Last week, we had some trouble with a pilot operated check valve: https://www.youtube.com/watch?v=Frn3f1WZdLM. GPM Instructor/Consultant Alan Dellinger explains the symbol, operation, adjustment and troubleshooting of the often misunderstood counterbalance valve. Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit. Maximum valve leakage at reseat = 5 drops/min. This valve has positive seals between all ports. Some actuators with running-away (or overrunning) loads will let the load free fall when the directional valve that controls the actuator shifts to lower the load.
